Fifteen castings of a certain type are produced per day in a foundry. The finished castings are inspected and classified as defective or non-defective. Records indicate that of the last 500 castings inspected, 16 were defective. Based on this information, find the following:
(a) The probability of having at no defective castings in a day's production
(b) The probability of having at least two defective castings in a day's production
The goal is to design and implement a high-speed logical shifter. The specification you have been given requires the design of a circuit that will shift a 16-bit word to the right or to the left by 1-,2-,3-, or 4-bit positions in a single clock ti..
